When it comes to the Industrial Internet of Things, the first thing that comes to mind is data transmission. To transmit massive industrial data from the equipment to the control center, wireless data transmission terminals play an important role. Let’s follow the editor today to see how its “connection” is established!

When it comes to wireless data transmission terminals, I believe the first thing that everyone thinks of is the DTU module. In fact, according to functional positioning, it can be divided into two categories:
One type is pure communication modules, which only include communication functions and are mainly used in various communication terminal products.
The other type is the DTU module, which has a built-in serial port and can directly connect to the serial port device, which is very convenient!
What I want to recommend to you here is the SeDTU200 series of DTU modules with extremely high cost performance in the industry. It is a typical second type DTU module.
First of all, the appearance design is very compact, even a mobile phone case is larger than it. The all-metal body has a protection level of IP30 and is fully suitable for industrial sites.
Then it has a built-in standard serial port interface, supporting RS232 and RS485, which can easily connect various sensors, PLC controllers, motion drivers, etc. Now that we have a serial port, wouldn’t it be much more convenient to connect devices?
Let’s look at the CPU and network parts again. It uses an industrial-grade MCU+4G module, cmbb, and its stability surpasses other communication modules! It supports the standard TCP/IP protocol stack and can perform transparent data transmission. It can be quickly operated without any modification. use.
The most important thing is that SeDTU200 is really powerful! It can support data conversion of different protocols, such as Modbus, MQTT and other industrial protocols. It can also realize the function of dual DTU hot backup, and automatically switch over when the main DTU fails to enhance communication reliability.
Through its conversion and forwarding functions, data from on-site serial devices can be transparently transmitted to the industrial cloud platform to achieve true digital management. Isn’t this the core value of the Industrial Internet of Things?
The editor feels that SeDTU200, a wireless data transmission terminal, is extremely competitive in terms of performance, functionality, and cost-effectiveness, and is very suitable for various current industrial field applications.
Next, follow me to open the black box of data transmission by the DTU module and see the mystery of its "connection":
1. First connect to the remote data center through the 4G network to establish a safe and reliable wireless transmission link;
2. Collect real-time data of field equipment through the serial port, which is the source of running water;
3. The data enters the "black box" of DTU after being encapsulated and securely encrypted;
4. Convert protocols within the “black box” and organize data formats according to rules;
5. The converted data enters the 4G module and is transmitted through the wireless network;
6 The data center analyzes the received data and sends control instructions;
The 7DTU module transmits instructions to the field equipment through the original route to complete closed-loop control.
Isn't it amazing? The data is in this seemingly simple DTU module, completing the magical industrial "networking" conversion.
If you are also interested in the DTU module, 
welcome to get detailed information about SeDTU200. In fact, the price is very affordable and will not destroy the budget of industrial control projects at all.
On the road to digital transformation, the DTU module is an important cornerstone, which allows sensor serial port data to be seamlessly connected to the Internet. As Lao Tzu said: "A late bloomer blooms"; a good DTU also needs to be verified over time to be truly stable and reliable.
With its excellent quality and high CP value, SeDTU200 will surely become an important promoter of the Internet of Things and industrial interconnection. I hope this self-media style product copy can help more friends understand the charm of DTU. Let us join hands to build a beautiful world where everything is connected!
